South Bali to Sumbawa seaplane charter currently rests on one publicly documented route: Santai Seaplane’s “South Bali – Sumbawa Charter Flight,” flown under its Indonesian partner’s Air Operator Certificate, PT Wisarada Sapanta Utama AOC 135-067, approved by the Ministry of Transport and DGCA Indonesia. No public fares exist as of September 2026. Juara Holding Group, an independent broker, takes your dates, pax count and board-bag list to a licensed operator for a real quote.
Everything below separates what an operator has actually published from what is still desk estimate or feasibility-on-request. That distinction matters more than any glossy brochure copy when you’re trying to plan a surf trip or a yacht rendezvous around a daylight-only, weather-dependent aircraft.
What does the published route actually say?
Santai Seaplane (PT Santai Seaplane Aviation), a subsidiary of Hong Kong-based Seaplane Asia Group, announced amphibious operations around Bali and Banyuwangi in a press release dated 25 December 2025 and updated in January 2026. That announcement named Banyuwangi Airport (BWX) as a key hub, with approved water-landing permits at the Banyuwangi water aerodrome, Menjangan in North Bali, and other water-landing sites in southern Bali. Services were stated to commence in Q2 2026, pending aircraft delivery and registration — so treat “operational” as a status to confirm on the day you inquire, not a guarantee baked into this page.
Table 1 lays out what the operator’s own South Bali – Sumbawa charter route page states versus what is still a desk estimate pending confirmation.
| Item | What’s published / verified | What’s desk estimate |
|---|---|---|
| Departure zone | South Bali water-landing site (per operator’s Q1 2026 announcement) | Exact pontoon/jetty confirmed only at booking |
| Destination | Sumbawa surf and yacht bays | Which specific bay depends on swell, tide and operator clearance that day |
| Operating authority | Flights run under partner AOC 135-067, PT Wisarada Sapanta Utama, approved by Ministry of Transport and DGCA | — |
| Block time | Not published by the operator | Desk estimate only, roughly 45-70 minutes depending on bay and routing — confirm with operator |
| Aircraft type | Cessna Grand Caravan amphibious (per operator’s North Bali hub announcement, 3 Jan 2026) | Exact tail assigned per charter, subject to availability |
| Pricing | Not published | Quote on request — see pricing model below |
| Status as of Sep 2026 | Route page exists; commercial service tied to Q2 2026 aircraft delivery/registration | Confirm live operational status before locking dates |
Nothing on this page invents a fare or a fixed flight time. If an operator page doesn’t say it, we label it a desk estimate and tell you to confirm it before you commit non-refundable plans around it.
Which Sumbawa bays can be landed?
The operator’s published route names Sumbawa surf and yacht bays as the destination class, without listing an exhaustive, guaranteed bay-by-bay landing schedule on its public page. In practice, water landings on this coast depend on three things every time: swell height at the specific bay, tidal window, and whether that bay carries the water-aerodrome clearances required under Indonesia’s Manual of Standard CASR Part 139 Volume III (SKEP/227/VIII/2010, updated by KP 206 Tahun 2021).
That standard — adapted from FAA AC 150/5395-1 — treats a water aerodrome as a certified, registered facility (CASR 139.101) with its own obstacle-limitation surfaces, visual aids and a Letter of Operational Coordination Agreement with AirNav Indonesia and the relevant maritime authority. A bay that looks flat and empty on a map is not automatically a legal landing site. Ask the operator, through this desk, which specific Sumbawa bay is cleared for the week you’re traveling — the answer can change with the season and with which sites currently hold active coordination agreements.
For yacht or phinisi rendezvous near Sumbawa, the same rule applies: the water landing has to fall inside a coordinated water-aerodrome area, not simply near your vessel’s anchorage. Send your boat’s planned position and we’ll check it against what the operator can confirm.
What does AOC 135-067 mean for me?
An Air Operator Certificate under CASR Part 135 is Indonesia’s commercial charter authorization — the license that lets an operator sell seats or whole-aircraft charters to the public, as opposed to flying under Part 91 for non-commercial operations. AOC 135-067, held by PT Wisarada Sapanta Utama, is the certificate under which Santai Seaplane’s published South Bali – Sumbawa route is flown, per the operator’s own route page.
Practically, that means three things for a booking:
- The flight is subject to Part 135 crew, maintenance and duty-time rules, not the lighter Part 91 regime.
- CASR Part 91 Amendment 5 equipment rules still apply on the water: one life jacket per person on board, sound-signal equipment meeting COLREGs, and an anchor plus sea anchor carried when needed.
- Charter pricing and scheduling are quoted per flight through the certificate holder’s booking channel — not sold as scheduled seats you can buy off a fare table.
Juara Holding Group does not hold this certificate, does not operate the aircraft, and is not affiliated with Santai Seaplane or PT Wisarada Sapanta Utama. We are an independent coordination desk, established 2015, that packages your trip requirements and puts them in front of licensed operators for a direct quote.
Surf boards, dive gear, and what happens if the swell is too high
Amphibious charter aircraft fly with strict weight-and-balance limits, and board bags or dive cylinders change the math fast. Table 2 covers what to plan for.
| Consideration | Detail |
|---|---|
| Surf-board carriage | Declare board length, quiver count and bag weight at inquiry — cabin and float-compartment space is limited on amphibious Caravans |
| Dive-gear carriage | Steel cylinders, BCDs and weight belts must be declared; some gear may need to travel separately by road/boat if weight allows |
| Weight and balance | Every charter is individually calculated per pax + baggage + fuel; the operator can decline excess weight rather than risk the landing |
| Cabin baggage limit | Not publicly listed — request the current limit when you submit pax and gear count |
| Alternate if swell is too high | Diversion to a Sumbawa land airport (e.g., Sumbawa Besar or Bima) is the operator’s call on the day, made for safety, not convenience |
| Facility tolerance | Amphibious handling facilities are designed for surface elevation variation up to 1.8 inches (0.457 m) — beyond that, a water landing may be scrubbed |
| Life-safety equipment | One life jacket per person, sound-signal gear per COLREGs, anchor and sea anchor per CASR Part 91 Amendment 5 |
Seaplane operations in this region are daylight-only, and every one of them is contingent on weather, tide and sea state — that’s an operating fact of amphibious aviation here, not a Santai-specific caveat.
How pricing works — because there’s no published fare
No verifiable IDR or USD price exists for this route as of 2026. Anyone quoting you a fixed per-seat rate without an operator confirmation is guessing. Charter pricing on amphibious routes typically builds from these variables instead:
| Pricing factor | Why it moves the number |
|---|---|
| Whole-aircraft charter | You’re usually quoted the full aircraft, not a per-seat fare |
| Positioning legs | Cost of flying the aircraft empty to your departure point and back |
| Number of stops | Each additional landing (fuel, handling) adds time and cost |
| Landing and handling fees | Water-aerodrome and any airport-alternate fees, where applicable |
| Weather repositioning | A scrubbed water landing that reroutes to a land airport can add ground transfer cost |
How booking works
- Send your trip window — dates, number of passengers, and departure preference (South Bali site) via WhatsApp or email.
- Declare gear — board bags, dive cylinders, or other bulky items so weight-and-balance can be checked early.
- Desk submits to the operator — Juara Holding Group forwards your request to the licensed operator’s booking channel; we do not set the price.
- You receive an operator-backed quote — including whichever Sumbawa bay is currently cleared, and any Part 135 conditions that apply.
- Confirm and reconfirm — because this route is daylight and weather-dependent, we recommend reconfirming 24-48 hours out.
Ready to check availability? WhatsApp Juara Holding Group’s concierge desk at 6281139414563, or email bd@juaraholding.com, with your travel dates, passenger count and board-bag or dive-gear list. We are an independent broker — not Santai Seaplane, not PT Wisarada Sapanta Utama, and not affiliated with either — and we’ll tell you plainly if a date can’t be confirmed rather than overpromise a landing.
Frequently Asked Questions
Is the South Bali to Sumbawa seaplane route actually flying right now?
The operator’s route page exists, but commercial service was tied to aircraft delivery and registration targeted for Q2 2026 in its own announcement. As of September 2026, confirm current operational status through this desk before you lock non-refundable plans — status can shift with fleet delivery timing.
Can I book just a one-way flight to Sumbawa, or is it round-trip only?
The operator hasn’t published a public fare structure distinguishing one-way from round-trip pricing. Charter aircraft are typically quoted for the full mission, including positioning legs, so tell us your intended itinerary and we’ll get a structure quoted rather than assume one.
How many passengers and how much luggage can the aircraft take?
Capacity depends on the specific amphibious Caravan assigned and the day’s weight-and-balance calculation with fuel, passengers and gear combined. There’s no fixed public number — declare your pax count and baggage (especially board bags or dive cylinders) and the operator confirms the limit for your date.
What happens if the sea is too rough to land at Sumbawa?
The operator can divert to a land airport in Sumbawa, such as Sumbawa Besar or Bima, at their discretion for safety. This is a standard contingency for daylight, sea-state-dependent seaplane operations, not a route-specific problem — build a buffer day into surf or dive trip plans around this route.
Does Juara Holding Group operate the seaplane or set the price?
No. Juara Holding Group is an independent coordination desk, established 2015, that forwards your request to the licensed AOC 135-067 operator and relays their quote. We are not Santai Seaplane, not PT Wisarada Sapanta Utama, and not a licensed aviation operator ourselves.
